 C2H5OH (Alcohol / Benzine) Gas Sensor Module
The C2H5OH (Alcohol / Benzine) Gas Sensor Module is designed to allow a microcontroller to determine when a preset C2H5OH gas level has been reached or exceeded. Interfacing with the sensor module is done through a 4-pin SIP header and requires two I/O pins from the host microcontroller. The sensor module is mainly intended to provide a means of comparing alcohol sources and being able to set an alarm limit when the source becomes excessive.
Features:
- Uses the MQ-3 C2H5OH Gas Sensor
- Easy SIP interface
- Compatible with most microcontrollers
